To all whom zit may concern.'

Be it known that we, GUsTAvE A. W. ScnrLLING and JOHN H. FLAoH, citizens of the United States of America, residing in the city and county of Denver and State of Colorado, have invented a new and useful Air-Inlet and Beer-Outlet Bun@- for Barrels, of which the following is a specification.

Our invention relates to improvements in the compressed-air inlet and bung-hole apparatus for beer-holding barrels and for other liquors that are kept on tap; and the objects of our invention are, first, to provide an improved adjustable air-inlet and removable bung for beer-barrels of different capacity, second, to provide a simple bung adapted to be threaded to the bung-holes of barrels and an improved aireinlet and beeroutlet valve-controlled pipethat is adapted to be held in barrels of different capacities by any predetermined part of the length of said air -inlet and beer outlet tubes, and, third, to provide a simple inexpensive airinlet and beer-drawing apparatus that can be changed from one barrel to another. We attain these objects by the mechanism illus trated in the accompanying drawings, in which- Figure 1 is a vertical longitudinal sectional view illustrating the application of our improved device. Fig. 2 is a front elevation of the improved bung. Fig. 3 is sectional view of the several parts constituting` the bung. Fig. 4 is a perspective view of the wrench used for removing the nut which is threaded within the bung. Fig. 5 is a perspective view of a device for removing the ung..

Similar letters of reference refer to similar parts throughout the several views.

Referring to the drawings, the numeral 1 designates a fragmentary part of the head of a beer-barrel which is provided with a bung- A slight enlarged counterbore is also preferably formed at the entrance of the bung-hole. Tn this bung-hole we thread. a plug 4, which is provided with a flange end that fits in the counterbore of the bung hole. This bung is provided with an axial aperture 5, which fits slidably a pipe 6, that extends slidably through the bung. This aperture is formed through the lower end of the bung, the upper j portion being provided with a counterbore 7, the entrance to which is threaded and a nut 8 is threaded to it. Between the bottom of this nut and the bottom of the counterbore we place arubber washer 9, which rests on the bottom of the counterbore, and a metal ber washer and the bottomof the nut. This nut is also provided with an axial aperture that fits slidably the pipe 6. The nut is also provided with two diametrically formed slots 11, which extend from the periphery of its axial hole radially into its surface and are adapted to receive the fingers 12 of a forked wrench 13, which are separated far enough apart to straddle the pipe 6.

The flange of the bung is provided with two oppositely-arranged holes 13A, in which which enables the bung to be screwed into or out of the barrel. This wrench is adapted to be used in a bit-stock. 13D is a screw that is threaded into the flange of the bung in a position so that its head will lap over onto the nut 8, so as to prevent the nut 8 from unscrewing from the bung whenever it is re* moved from one barrel and before it is placed in another barrel.

The pipe 6 extends through the bung a predetermined distance, Which depends on whether it is to be applied to barrels, halfbarrels, and kegs, it being made to extend to the bottom of these sizes of barrels.

and is threaded to a pipe Ti-fitting 14, to the central entrance of which it is threaded. This Tefitting 14 is of special construction interiorly, and it contains an entrance-passage 15 and an outlet 16, which enter its opposite ends. These entrances are separated by a partition 17, which projects down into one side of the center entrance, to which the pipe 6 is connected, but at a short space from its side sufficient to form a passage from the entrance 15 into the center entrance 15A to the T 14 and to the pipe 6.

A diaphragm 18 is formed across the center inlet at its junction with the end entrances, and a threaded aperture is formed through it, in which a pipe 19 is threaded. This pipe 19 is enough smaller in diameter than thepipe 6 to extend loosely through it and leave a small Aannular space all around it, and it is also washer 10, which is placed between the rub-- pins 13B, that are formed on a wrench 13C, iit

This

tube extends throughv and above the bung.

made a little longer than the pipe 6, and it connects with the end outlet of the T 14,

4while the pipe 6 connects with the center inlet A of the T. The lower ends of these two pipes are threaded to a plug 20, which has a central recess in it that connects with and into and through the outlet 16 of the T- iitting, as will be more fully explained hereinafter.

The pipe 6 is an air-feed pipe. Its, lower end is closed by the plug 2O 3 but it is provided with a circumferential row of air-outlet holes 22 at a predetermined point in its length relative to the size of the beer-barrel it is to be placed in; but they are placed in each case close to the bung, and the lower ends of the tubes 6 and 19 extend to the bottom of the keg. To the ,inlet 15 oi the T a hose-coupling 23 is threaded, which is adapted to be connected by a hose to a supply oi" compressed air, and to the inner end ot' the hosecoupling an automatically-operating rubber valve 24 is secured, which is of a type in use for this purpose and does not form in itself a part of our invention. To the outlet 16 of the T 14 a spigot 25 is threaded, which is provided with an outlet which is connected to a hose-coupling 26 and is controlled by a hand operating-valve 27 and is the beer-drawing outlet.

The operation is as follows: The bung is screwed into the threaded bung-hole in abeerbarrel, half-barrel, or keg lilled with beer, its aperture 5 being closed by a cork to prevent the escape of the beer. Now when it is desired to tap the barrel the nut S is loosened and the air and beer tubes are pressed into the rubber washer and the bung, so as to dislodge the cork, and are pushed through until they rest on or close to the bottom head of the barrel, half-barrel, or keg, as the case may be, and as the air-holes in the air-pipe have been formed for either a full barrel or a half-barrel or a keg they will be located just below the bung and close to it, either just above or at the edge of the beer in the barrel or keg. The nut is then screwed against the rubber washer and compressed the rubber washer against the air-tube, making an air and beer tight joint. A supply of compressed air is then connected to the air-inlet end 15 of the T 14, and the air flows through the rubber valve 24 and the tube 6 and out of the air-holes 22 into the barrel or keg of beer, charging it with air until it has reached the desired pressure, and the beer under this pressure flows into the pipe 19 and through the outlet of the T to the spigot, where it is ready to be drawn when wanted.

After the beer has been sufficiently charged with air the connection with the supply is disconnected, and the rubber valve 24 is closed by the back pressure of the air and beer.

Our invention is simple, durable, and practicable, and can be interchanged from one barrel to another.

Having described our invention, what we claim as new, and desire to secure by Letters Patent, is-
